What does EC code mean on hot tub?

The "EC" code displayed on a hot tub panel indicates that the spa is operating in Economy Mode. This is an energy-saving setting, not an error code.

What is EC Mode?

EC Mode, short for Economy Mode, is an operational setting in many hot tubs designed to reduce energy consumption. Unlike a standard mode that continuously maintains the set temperature, Economy Mode optimizes heating to minimize electricity usage.

How EC Mode Works

In Economy Mode, your hot tub will only activate its heater to reach the set temperature during its pre-programmed filter cycles. This means that if the water temperature drops below your desired setting outside of these specific filtration periods, the heater will remain off until the next scheduled filter cycle begins. This contrasts with other modes, such as Standard Mode, which typically aim to keep the water at the set temperature around the clock.

Display Characteristics of EC Mode

When your hot tub is set to Economy Mode, you will see "EC" appear on the control panel display.

• This indicator often shows up when the water temperature reading is not current.
• The "EC" display will also frequently alternate with the current water temperature reading while the hot tub's pump is running. This alternating display serves as a clear signal that the spa is operating under its energy-efficient settings.

Important Clarification: Not an Error Code

It is crucial for hot tub owners to understand that the "EC" display is not an error code. Many users might mistakenly interpret it as a problem or malfunction. Instead, it simply confirms that the hot tub is functioning as intended in a specific, energy-saving operational mode.

Changing EC Mode

If you wish to switch your hot tub out of Economy Mode, or activate it, the process is generally straightforward. While specific button sequences can vary slightly between hot tub models, a common method involves pressing the "Warm" or "Cool" button, followed by the "Light" button on your control panel. Always consult your specific hot tub's owner's manual for the most accurate instructions.

Why Use Economy Mode?

Utilizing Economy Mode offers several benefits, primarily related to efficiency and cost savings:

• Energy Conservation: By heating only during filter cycles, the hot tub's heater runs less often, leading to reduced electricity consumption.
• Lower Operating Costs: Less energy usage directly translates to lower utility bills, making your hot tub more economical to maintain.
• Environmental Responsibility: Conserving energy helps reduce your household's overall carbon footprint.
• Ideal for Infrequent Use: If you don't use your hot tub daily or are away for extended periods, Economy Mode can maintain a warm enough temperature without the constant energy drain of continuous heating.
